Abstract: PURPOSE: To absorb the earthquake energy by superposing two steel plates with anchors between a pile head part and a foundation structure part, and by arranging a base isolation system in which synthetic chemical materials having a cushioning performance have been attached to the upper surface and to the side surfaces. CONSTITUTION: An embedded mold 9 is provided in the empty part of a pile head part 1, and a lower steel plate 6 fitted with anchors is installed in the pile head part, and grout is filled through a grout injection hole 10. After hardening of grout, synthetic chemical materials 4 having a cushioning performance are attached to the side surfaces 3 of both the pile head part 1 and the lower steel plate 6.

Title: Controller and control method for induction motor
Inventor: FUNAKURA SEIICHI
IPC: H02P27/06
Filed: 1995-05-29
Abstract: PURPOSE: To accelerate an induction motor smoothly even under an overcurrent state by controlling the acceleration gradient of a load when an overcurrent is generated during acceleration gradient control. CONSTITUTION: An overcurrent detector 22 outputs a signal when a voltage corresponding to the output current from an inverter exceeds a level being set by an overcurrent level setter 23. An acceleration gradient generator 26 generates a data indicative of an acceleration gradient command required for acceleration operation. When the overcurrent detector 22 produces no output, an acceleration gradient under steady condition being set by an acceleration gradient setter 21 is delivered, as it is, from the acceleration gradient generator 26 to an output frequency command generator. When the overcurrent detector 22 generates an output, a negative acceleration gradient is delivered to the output frequency command generator.  When an overcurrent reset detector 25 detects resetting of overcurrent, an acceleration gradient lower than that prevailing immediately before becoming an ocvercurrent is delivered to the output frequency command generator. Consequently, an induction motor can be accelerated smoothly even in an overcurrent state.

Title: Production of indole
Inventor: TANAKA MAKOTO
IPC: C07D209/06
Filed: 1987-06-24
Abstract: PURPOSE: To obtain indole of high purity economically in high recovery rate by precipitating crude indole crystals crystals from cooled crude indole, washing the crude crystals with a aliphatic hydrocarbon and/or alicyclic hydrocarbon solvent and drying.  
     CONSTITUTION: Crude indole oil separated from coal tar or the like is cooled to precipitate indole crystals. The crude crystals are washed or rinsed with an aliphatic hydrocarbon and/or cyclic hydrocarbon solvent boiling at 30W200°C and dried to give indole of high purity, useful as a starting substance for medicines and agrochemicals. The process can recover indole of high purity in low running costs in high recovery regardless of the concentration of the starting indole. For example, even in case of low indole concentration, e.g,. 83%m pure indole of 98W99% purity can be recovered in about 83% yield, further the amount of the solvent needed is very small such as 1.3 time that of the starting oil.

Title: Semiconductor light emitting diode
Inventor: UJI TOSHIO
IPC: H01L33/14
Filed: 1982-09-07
Abstract: PURPOSE:To remarkably improve the linearity of a current-optical output property by a method wherein the sectional area in the direction horizontal to the main surface of the substrate of a conductivity type semiconductor layer is more increased as it is close to an active layer. CONSTITUTION:The region of current flow in a P type clad layer 11 is strictured by a region 13 surrounded by an N type or high resistant semiconductor layer 12. The diameter of the stricture region 13 is more increased as it is closer to the active layer 15 from the point D1 nearest to a P-electrode 14. When current is made to flow from the P-electrode 14, the expansion of the current more enlarges as it is closer to the active layer 15. The expansion of the current becomes larger as the current value is smaller. The variation of this current expansion increases more remarkably than conventional, therefore the change of the luminous diameter compared with current further increases more than conventional.
